Application filed a uary 20,1906. Serial No. 296.934.

To all whom it may concern: Beit known'that I, MELVIN W. PALMER, acitizen of the United States, and a resident of Catskill, in the countyof Greene and State of New York, have invented certain new and usefulImprovements in Liquid-Freezers, of which the following is aspecification.

My invention relates to liquid-freezers, and particularly to ice-creamfreezers. 1o It has for its object to provide an ice-cream freezer ofthe character embodying a rotatable cylinder adapted to contain afreezing mixture and be operated from either side through a receptaclecontaining cream to take up and freeze layers of the cream upon itsouter circumference and deliver it from either end, thereby convenientlyadapting the freezer to be operated from and to deliver ice-cream fromeither side of a counter or table on which'it may be fastened or placed.

It has for a further object to provide a device of the character setforth embodying ad vantages in point of perfect "operation, sim- 2 5plicity,inexpensiveness, and durability.

In the drawings, Figure 1 is a plan view of my freezer with the coverremoved Fig. 2, a longitudinal vertical sectional view; Fig. 3, atransverse vertical sectional view, and Fig. 4 3 a detail view of one ofthe end pieces having the adjustable plate for resiliently supportingthe scraper-chute.

In all the figures of the drawings like reference characters designatecorresponding 3 5 parts.

Referring to the drawings, 1 designates the casing, and 2 the covertherefor, the sides 3 of, the casing having vertically-extending grooves1, adapted to receive and removably 4o retain the interchangeable'endpieces 5 and 6 in place.

' The cylinder 7 is rotatably mounted in the casing upon a journal 8,secured to one side thereof and having a squared end adapting it '45 toreceive a crank for turning. the cylinder from'one side and a neck 9,projecting from the other side thereof and serving as an openfor theintroduction of the freezing mix "-ture, which may. consist, as usual,ofcracked 50.ice and salt, said neck having its outer end spirallythreaded to adapt 'itto'receive a spirally-threaded removable closin-cap' 10, to which a bar 11, similar to that orming the journal 8, issecured to. adapt it to receive a 5 5 crgnk for turning thecylinder-from the other s1 e. a

A pan 12, adapted to receive the cream to be frozen, placed in thecasing beneath the cylinder, said pan having straight sides to give it afirm seat upon the bottom of the cas- 6o ing, and thus prevent rocking,and a rounded bottom 13, somewhat conforming to the circumference of thecylinder, so that the cream will run directly under the center of thecylinder in a position to be readily taken up thereby. The neck of afunnel 114 extends through the end piece5 to a position over the pan toafford means for the convenient introduction of cream into said pan andis provided with a stop-cock 15 to control the feeding of the cream.

A removable scraper-chute 16 is removably journaled in bearings 15 inthesides of the casing over the end piece 6, so that its upper end willcome near the circumference of the cylinder to thereby remove the creamfrozen thereon and deliver it into a receptacle. Means is provided foradjusting said scraper so that the upper end can be brought into theproper relation to the circumference of the cylinder and resilientlyheld, so that it will adjust itself to any unevenness of the surface ofsaid cylinder, said means comprising a plate 17, slidably retained onits end piece 6"85 by a keeper 19, the" upper end having a rou'ndedspring projection adapted to bear against the under surface of thescraper-chute and the lower end provided with a spring-pressed f pin 20,adapted to engage the holes 21 in the 0 end piece one at a time and holdthe plate in its adjustedposition; Bearings 22 are also provided in theopposite ends of the sides of. the casing to that of the bearings 15,said bearings being for the purpose of receiving the journals of theremovable scraper-chute when the operation of the freezer is reversed.Itwill be understood that to reverse the operation of the freezer thecrank is removed from the journal .8 and placed on the bar 11, thescraper-chute 16 and end pieces removed, the end pieces exchanged inposition, and the journals of the scraper-chute then mounted thebearings 22', so that the upper end of the scraper will bear against orcome close to, circumference of the cylinder from the opposite end ofthe casing, and finally, if necessary,

the plate 17 is adjusted to resiliently hold the upper end of thescraper-chute in its proper relation to said cylinder. I do not wish tobe understood as limiting; 'myself to the precise details andarranger:rent

casing in line with the cylinder, removable interchangeable end pieces,an. adjustable platemounted on one of said end pieces and-having aprojection adapted to bear against and support the lower end of thescraper-chute and a funnel mounted in the other-one of said end piecesand projecting into said-casing over said pan, substantially asdescribed. 4 I
